PATENT IVER LORENTZEN, OF CLEAR LAKE. SOUTH DAKOTA.

NAIL-FULLER.

Application filed March 21, 1921.

To all whom it may concern Be it known that I, IVER LoREN'rznN, acitizen of Germany, residing at Clear Lake, in the county of Deuel andState of South Dakota, have invented certain new and useful Improvementsin Nail-Pullers, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to nail pullers, and particularly to that classof nail pullers wherein the head of the nail is clamped between twoheads and the closed heads rocked to withdraw the nail.

The general object of my invention is to provide a very effective deviceof this character having jaws which may be driven into the wood on eachside of a nail by the application of a hammer to the head of theimplement and these jaws then closed, one of the jaws being formed toprovide a rounded or cam-like surface acting to cause the implement towithdraw the nail upon the rocking of the implement.

A further object is to provide a device of this character with coactingwire cutting blades or members.

My invention is illustrated in the accompanying drawings, wherein Figure1 is an elevation of my device showing the jaws closed;

Fig. 2 is a fragmentary elevation showing teh jaws open and in appliedposition for being forced into gripping engagement with a nail;

Fig. 3 is a perspective view of the head 10 and its jaw;

' Fig. 4 is a perspective view of the head 11 and its jaw.

Referring to these drawings, it will be seen that this implementcomprises two heads 10 and 11. The head 11 is recessed upon one face, asat 12, the rear wall of this recess being concavely curved, as at 13.Attached to this head 11 is the handle 14. The head 10 is also recessedupon one face. as at 15, to confront the recessed face 12 of the head 11and the rear edge of the head is curved to conform to the curvature 13of the rear wall. This head is provided with the handle shank 16. Theseheads 10 and 11 are pivoted to each other for rotation around a commonaxis by means of the pivot pin or stud 17 The head- 10 is formed withthe outwardly Specification of Letters Patent.

projecting jaw 18 whose inner face is concavely curved, as at 19, toform a tooth 20, and the head 11 is correspondingly formed with anoutwardly projecting jaw 21 whose face confronting the jaw 18 isconcavely curved to form the biting or cutting tooth 22. Thus when thesejaws are forced together a space is left between the concavely curvedconfronting faces of the jaws. These j aws, it will be seen, are of thefull width of the implement.

At the base of the curved face 19 the head 10 is formed with a squarerecess and the head 11 with a square recess 24:. When the jaws areopened to a certain point, these recesses are in register with eachother but when the jaws are closed by forcing the handles 14 and 16toward each other, the recesses 23 andv 24 will be out of alinement.These recesses, therefore, may be used for cutting wire in an obviousmanner, the wire being disposed through these recesses when the jaws areopened and then the jaws closed to cut the wire. The head 11 is formedopposite its jaw 21 with a flat face 2 In the use of this device as anail puller, the jaws are opened and disposed on each side of a nail, asillustrated in the drawing, and then the hammer is applied to the face25 to drive the jaws into the wood on each side of the nail. lVhen thetoothed ends of the jaws have been driven a sufficient. distance underthe wood, the jaws are closed on the nail and then the device is rocked,as upon the curved face 26 of head 10, thus acting to pull the nail outof the wood. This device will not only pull nails having heads but maybe also used to offectively pull nails whose heads have been broken off.It may be also used as a staple puller and as a wrench and is especiallyuseful in removing nails from boards nailed in an upright position. Itwill be obvious that the device may be made of various sizes and that ithas a large range of usefulness.

I claim An implement of the character described comprising two headsrecessed upon their confronting faces and having handles, the headsbeing pivoted to each other for rotation around a common axis, both ofsaid heads having integral outwardly projectin confronting jaws, theconfronting faces of the jaws being concavely curved, the eX- tremitiesof the jaws being thereby formed with confronting biting teeth, one ofsaid heads being thickened at its rear end immediately above the pivotalaxis of the heads and formed with a flat face whereby a hammermay beapplied to the implement, the

wall of the recess in the head having the thickened portion resting atall times upon the periphery of the other head. 10

In testimony whereof I hereunto aflix my signature.

IVER LORENTZEN.
